McAfee Integrity Control provides an effective way to block unauthorized applications and change on fixed-function point-of-service infrastructures, including ATMs, point-of-sale (POS) systems, and kiosks. It combines industry-leading whitelisting and change control technology to ensure that only trusted applications run on fixed-function systems. Unlike simple application control, Integrity Control uses a dynamic trust model that eliminates the need for tedious manual updates to approved lists, so even when systems are locked down, software updates from authorized sources are still allowed.
